Title:
DISPLAY SUBSTRATE AND METHOD FOR MANUFACTURING SAME, DISPLAY PANEL, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/176815
Kind Code:
A1
Abstract:
A display substrate and a method for manufacturing same, a display panel, and a display device. The display substrate comprises a substrate base (100), first display areas (111) and second display areas (112), located on the substrate base (100), alternately arranged along a first direction, a parallax barrier (200) located at a light exit side of the display substrate, and first phase retardation films (300) located at the light exit side of the display substrate. The parallax barrier (200) comprises light-shielding parts (210) and light-transmissive parts (220) alternately arranged along the first direction. Each light-transmissive part (220) comprises a first light-transmissive area (221) and a second light-transmissive area (222) along the first direction. The first light-transmissive area (221) completely falls into an orthographic projection of the first phase retardation film (300) on the parallax barrier (200) and the orthographic projection of the first phase retardation film (300) on the parallax barrier (200) does not overlap the second light-transmissive area (222). The first phase retardation film (300) is configured to make polarized light emitted from the first light-transmissive area (221) and the second light-transmissive area (222) of the display substrate different in polarization direction. The display substrate achieves the purpose of increasing a viewing angle by combining the parallax barrier and the phase retardation films.
